What is described as deceleration, absorption or cocking phase?

• A. Eccentric component
• B. Concentric component
• C. Amortization component
• D. Isometric component

Answer: (A)

Eccentric contraction involves deceleration and energy absorption, and the cocking phase is part of this lengthening of the muscle. During the eccentric phase, the muscle lengthens while under tension, which slows the moving limb and stores energy for a subsequent explosive concentric action. The cocking phase in throwing is a loaded position reached during this lengthening. The amortization phase is the brief transition between eccentric and concentric actions, not the deceleration/absorption itself. Concentric is the shortening action that produces movement, and isometric is holding a position without length change.
